JOSEPH OSTERMANN, OF PHILADELPHIA, PENNSYLVANIA.

BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 585,780, dated July 6,1897.

A li ti 1 d July 20, 1896. Serial No- 599,860. (No model.) I

-. .To ctZZ whom it may concern.-

Be it known that I, JOSEPH OSTEBMANN, a citizen of the United States,residing at Philadelphia, (Manayunlg) in the county of Philadelphia andState of'Pennsylvania, have invented a new and useful Improvement inBicycle-Bells, of which the following is a specification.

My invention relates to that class of bells for bicycles in which thesounding of the bell is due to the friction contact of the wheel of themachine and the periphery of the disk carrying the clappers; and itconsistsin mounting the clappers loose on a revolving disk, said diskrevolving on a fixed shaft, to which shaft is fixed one or twocup-shaped bells. The loose clappers, when the disk is put in motion bya contact with the wheel of the bicycle, will cause the clappers to flyout, strike and sound the bell. I attain these objects by the mechanismillustrated in the accompanying drawings, in which Figure 1 is a sideView of a portion of a front bicycle-wheel,fork, and handle-bar with myimproved bell attached. Fig. 2 is a side view of the disk for carryingthe clappers. Fig. 3 is a vertical section of Fig. 2. Figs. 4 and 5 areviews of the clappers. Fig. 6 is a view of the screw for carrying theclapper. Fig. 7 is a side view of the bell, disk, and holding-frame.Fig. 8 is a top view of Fig. 7. Figs. 9 and 10 are views of thebell-cup.

Similar numerals of reference refer to like parts in all figures.

1 represents the disk, which maybe made of any suitable metal, cast orforged. On each side of the center web of this disk, and in a verticalline, are made projections 2. (See Fig. 3.) These projections beinginline, one will balance the other. The periphery of this disk is madeconcaved, so as to fit the curve of the wheel-tire.

3 represents the bell-clap per, made of iron,

and may be forged or cast. The clapper 3 is connected to the disk 1 bythe screw 4., and so connected that it may freely slide between theprojection 2 and the head of the screw 4.

The hole in the clapper being much larger than the stem of the screw 4permits it to fly out by the centrifugal force when the disk is put inrapid motion.

5 represents the bell, made of any suitable bell-metal, and may be castor forged cup shape, having a hub and a strikingdug 12. (See Fig. 9.) Inthe hub of the bell is formed a key-seat 7, by which it is keyed toshaft 8, which shaft passes through the frame 6, bells 5 5, and disk 1.At each end of the shaft 8 is cut a screw-thread, uponwhich thread arescrewed milled nuts 13.

The frame 6, carrying the bells, is jointed to a clip, which clip isfastened to the fork of the bicycle-frame.

9 is a connecting-cord connecting the frame 6 to a ring 10.

11 is a fixed hook under the handle-bar.

The operation of my improvement is as follows: When it is desirous tosound the bell, the ring 10, connected to cord 9, is unhooked from thehook 1-1, and the disk 1 will rest on the tire of the bicycle-wheel,which, if in motion, will give the disk a rapid revolving motion. Therapid revolving motion of the disk will by centrifugal force cause theclappers 3 to fly out, as shown by dotted lines on Fig. 2, and as theypass the lug 12 will strike it and sound the bell. When the bell is notdesired to ring, the ring 10 is hooked on the hook 11. This raises thedisk 1 from the wheel-tire, stops its revolutions, and the bell is mute.When desired,the rider of the bicycle puts the sound ing mechanism intocontact with, and by the operation of the bicycle-Wheel the bell willcontinue to ring as long as the rider chooses to maintain the contact.

The drawings show a double or two bells on the shaft 8; but it isobvious a single bell with one or two clappers placed on one side of thedisk may be used.

Having, as above, fullydescribed my invention, what I claim as new, anddesire to secure to me by Letters Patent, is

A bicycle-bell and means for operating the same, consisting of thecombination of the following elements: one or two cup' shaped bells,

each bell provided with a striking-lug, a revolving disk carrying one ormore loose clappers, a steering-wheel of a bicycle, means for puttingthe disk into and out of contact with the steering-wheel; whereby whenin contact the steering-wheel gives a rapid revolving motion to thedisk; the centrifugal force causes the clappers to fly out, strike thelug and sound the bell, all substantially as shown and described.
